Real-time 3D pixel-art boxing arena browser game

GOAL: Build a real-time 3D pixel-art diorama of a championship boxing night (three.js r160, orthographic isometric camera, low-res render with depth outlines and a fixed 67-colour OKLab palette, quarter-turn rotation, follow camera). MOTION: A full arena: ring on a platform with an emblem canvas, red/blue/neutral padded corners, four ropes per side that deflect when a fighter is driven onto them, ring steps; three judges' tables, a press desk with the timekeeper's bell and commentators, photographers with flashes; chairs on the floor, LED barrier boards with scrolling text, seven-row stands with ~950 instanced fans who sit, stand, cheer, gasp, clap, chant and hold up phone lights; a tunnel with smoke and a red carpet; a hanging jumbotron showing a live feed from a second tiny camera. Six fictional middleweights with styles (swarmer, slugger, counterpuncher, out-boxer, pressure fighter), orthodox and southpaw. Fighters are box rigs posed every frame: bladed stance, stepping feet, two-bone IK arms; ten punches as glove paths with hip/shoulder rotation; blocks, slips, ducks, parries, step-backs; head snaps, body-shot folds, staggers; knockdowns (sit, flat, knees) and getting up. Full night flow: ring walks with dimmed house lights and follow spot, MC introductions, referee instructions, rounds and corner breaks with stools and cornermen, clinches and breaks, knockdown counts with mandatory eight and three-knockdown rule, referee/corner stoppages, three judges scoring the 10-point must system, decision reading, arm raised, belt ceremony with confetti, champion defends next. The viewer works a corner: call a plan, get the crowd chanting, or throw in the towel; choose rounds and round length. Synthesized WebAudio sound. English UI, single dark theme, stacked phone layout.
